Paper Abstract

To correct erroneous data arising from a variety of methods for monitoring soil drought, the paper presents the analysis of the crop-canopy spectral characteristics and measured field moisture in the mid-late stage of wheat grain filling by means of observations of synchronously monitoring drought at Satellite -airborne - in situ observation in an experiment made in the low land of the Yellow River reach in a Zhoukou farm of the province on 23 May, 2009. Results suggest that (1) In the later time of wheat grain filling, there was no clear absorption valley in the domain of 1175nm, and it is different from the spectral chart in the period of turning green to heading. (2) There are data distortions in the domain of 1541nm and 2053nm which make out that the spectral in these domain are disable for retrieved the wheat canopy character. (3) The relationship of one depth to adjacent is better and the soil moisture in deeper depth could be deduced from its relationship with surface water content. (4) The retrieved results of FY-3A are not better than MODIS', but the accuracy has been to meet the current demand for services, and can be applied to operation.
